(1) high-life, high reliability: no mechanical parts solid state relays, solid state devices is completed by a contact function, because there is no movement of parts, and therefore able to work under high shock and vibration environment, since the composition of the solid state relay components the inherent characteristics, determines the long life of solid state relays, high reliability.

(2) high sensitivity, small power control, electromagnetic compatibility: solid state relay wide input voltage range, low-power drive is compatible with most logic integrated circuit without additional buffers or drive.

(3) fast conversion: Because the use of solid state relays solid state devices, so that the switching speed can be from a few milliseconds to a few microseconds.

(4) electromagnetic interference small: solid state relays do not enter "coil" no touch ignition arc and rebound, thus reducing electromagnetic interference. Most AC output solid state relay is a zero voltage switching at zero voltage turn-on, turn-off at zero current, reducing the sudden interruption of current waveform, thereby reducing the effect of switching transients.
